Solar Collector Operation
The special solar coating on the surface of the tank causes the heat transfer fluid in the tank to be heated when exposed to sunlight.
This means the system produces 150 litres of heat transfer fluid during the day at temperatures up to 85 degrees celsius.
The cold water inlet is connected to the house cold water supply. When hot water is drawn, the cold water flows through the heat exchanger
and is heated up and delivered to the point of use where it will be mixed down to the desired temperature.
Depending on the temperature of the system, up to 380 litres of hot water at 40 degrees celsius will be available.
To maintain the temperature in the tank, it is encased with 50 mm thick insulation of high-quality expanded polypropylene foam (EPP).
The system produces lots of hot water throughout the year, however occasionally after a few cloudy days, it may need a boost from the installed standby electric heater.
